Im a half and half, i love hardtail mid 90's marins, mainly because its what i used to ride back then. However theres plenty of other more exotic bikes on my if money were no object shopping list.
If money, space and time weren't limiting factors I'd probably have two of eveything (one for riding and one for spares), although there are some brands that really don't interest me.
But as thats not the case I'm somewhere in between. There is a dominant brand amongst my collection of bikes as well as a couple of typical choices.
If I was forced to reduce the size of the flock then I'd probably end up a one brand man.
